Feature
- I2C devices can be controlled from PC, RPI, etc. via serial COM port.
- Ideal for checking the operation of I2C devices and rapid prototyping.
- PL2303GL for serial COM conversion and SC18IM704 for serial I2C conversion are used.
- You can control I2C devices with easy commands via serial COM port from Teraterm, Node-Red, Unity, Python, etc.
- I2C has a Grove compatible connector.
- The power supply and pull-up resistor of the Grove compatible connector supports 5V/3.3V with a switch.
*Before connecting USB or I2C devices, please check the silk on the board and then switch 5V/3.3V.
*Please be careful not to apply 5V to 3.3V only devices.
Detail
- Please refer to the data sheet (PDF) for serial I2C conversion SC18IM704 commands.
- The default baud rate of serial I2C conversion SC18IM700/SC18IM704 is 9600bps.
- Use an I2C hub when connecting multiple devices with different addresses.
- By using the pin header on the board, it can also be used as a conversion board for SC18IM704.
- Equipped with a resettable fuse rated at 350mA on the USB5V power input side.
- The maximum current that can be supplied is around 150mA on the 3.3V line, and 350mA on the 5V line.
- If there is no response to the command, short-circuit the RST pin and GND pin with tweezers to reset.
